CASEMATIXCrypo Wallet Case Compatible with Ledger Nano S, Ledger X, Trezor Model T, Trezor One Bitcoin Cryptocurrency Wallet and Cables

I often carry my Aranet4 back-and-forth from office to home and when traveling as well. Previously, I used a small tin case to protect the device, but it wasn’t ideal. This case is well-made, light, and the perfect size and you can use the Aranet4 with the unit in the case, as long as the zipper is partially open and readings are quite accurate compared to the unit not being in the case.

-Good zipper quality (I’m very picky and hate it when zippers fail)-The small square foam padding inside that is compressible keeps things inside in one spot and provides a very snug fit.-The little elastic mesh pouch on one side is a nice add and has a good design. I could use it for a small charging cable but I actually don’t use it (battery powered device is in mine). The elastic band is stretchy enough to stretch around a device that fills the entire empty cavity of the case which also provides a nice stabilization/protection feature of the device that is inside in the scenario where you drop it or it is moving around a lot in a bag etc…-Finally…no weird smell from off-gassing like some of the other “hard case” out there

Perfect fit for the Aranet4. I used an exacto knife to punch about 10 small square holes in it (about the size of the head of a q-tip), which is easily done if you have a quality knife. Ventilation is great after doing so, I don't even have to take it out of the case to get a reliable reading.

I bought this to protect my Aranet4 but when zipped inside of it, it does NOT give similar readings as when outside of the case. Other comments here had said it worked fine, which was deceiving. And seeing how nice of a zipper it has, it doesn't seem logical anyway. It needs access to the surrounding air. Also it did off gas an odor when first received if you put your nose up to it. I left it outside to air out a few days. Seems like a nice case, but had wished the Aranet4 worked inside of it, without poking holes in it.

Using it to hold my Aranet4. Nice little case, but not cushioned.
